CROSS REFERENCE TO RELATED APPLICATIONS

The present application claims the benefit of U.S. Provisional Patent Application No. 61/622,837, filed on Apr. 11, 2012 and entitled “Toy Building Blocks,” which is herein incorporated by reference in its entirety.

BACKGROUND

1. Field of the Invention

The present invention relates to building blocks for modular construction. More particularly, the present invention relates to toy building blocks which are releasable and connectable.

2. Description of the Prior Art

Modular building blocks are useful for building a variety of static structures, including scale-modeled structures which are built for entertainment and educational purposes.

Toy building blocks and building block sets typically have male coupling components and female receiving components. Often, one surface of the block is dedicated to the male coupling components while the female coupling components are fashioned on a separate surface of the block. Consequently, such blocks are connected to one another in a stacking fashion where, for example, a bottom surface, having the female components, frictionally engages with a top surface, having the male components. There may be limits, however, as to what type of static structure can be built when using this stacking fashion. The stacking fashion method also necessitates a type of platform in which to build from so that the static structure can stand erect.

Building blocks relevant to this disclosure are discussed in the following U.S. Patents, which are hereby incorporated by reference: U.S. Pat. Nos. 4,606,732; 4,676,762; 5,000,713; 5,644,387; and 7,988,516.

DETAILED DESCRIPTION

Non-limiting embodiments of the present invention utilize construction components that are especially suited to construct modular static structures from varying interconnections.

Referring to the drawings, wherein like reference numerals represent like parts throughout the various drawing figures, FIG. 1 is directed to a toy building block 10. The polyhedron toy block 10 with multiple faces 20, 30, 40, 50, 60, and 70 (only faces 20, 30, and 60 are viewable in FIG. 1) includes a coupling region 80 which is made up of a pair of connector pegs 82, 84 and a pair of connector holes 86, 88. Faces 20, 30, 40, 50, 60, and 70 can also be void of a coupling region or regions 80 to provide a flat surface or a finished-face surface that cannot be coupled to another toy block 10. (See FIGS. 7-9). In FIG. 1, toy block 10 further includes an abutment region 90, as shown on faces 20, 30, and 60.

With continuing reference to FIG. 1, toy block 10 can be a convex polyhedron or a cube-shaped block with six quadrilateral faces 20, 30, 40, 50, 60, and 70 (only faces 20, 30, and 60 are viewable in FIG. 1). Complete views of coupling regions 80, which include a pair of connector pegs 82, 84 and a pair of connector holes 86, 88 are shown on faces 20, 30, and 60, in FIG. 1.

Toy blocks 10 may be composed of any rigid and resilient material such as, but not limited to, acrylonitrile butadiene styrene (ABS). Other materials that may be used include, but are not limited to, injection molded plastic and nylon. The structure of the block 10 may be solid, hollow, partially hollow, and/or may include a skeleton support structure or internal scaffolding (not shown). Blocks 10 may be of any color, combination of colors, or transparent. By way of a non-limiting example, toy building blocks 10 are conveniently sized as 1 cubic inch, 2 cubic inches, and 4 cubic inches.

Referring to FIG. 2, face 20 is shown with coupling region 80. By way of a non-limiting example, coupling region 80 includes connector pegs 82 and 84, as well as connector holes 86 and 88. The pair of pegs 82 and 84 is positioned along the diagonal line D1 of face 20. The pair of holes 86 and 88 is positioned along diagonal line D2, while the coupling surface 80 is fashioned in a radial orientation from an imaginary center point (not shown) on the toy block's 10 surface 20 in FIG. 2. When the coupling surface 80 is located in the center of face 20, 30, 40, 50, 60, and 70, an abutment region 90 is formed around the coupling surface 80, for adjacent contact with the abutment region 90 of another, corresponding toy block 10.

With continuing reference to FIG. 2, in a non-limiting example, each peg 82, 84 can be a hollow cylinder divided into four equal peg segments P1, P2, P3, and P4. Each of the peg segments P1, P2, P3, and P4 can include a corresponding lip portion L1, L2, L3, and L4.

In FIG. 2, each connector hole 86, 88 includes a bevel edge B for frictional engagement with the peg segments' (P1, P2, P3, and P4) lip portions (L1, L2, L3, and L4).

Referring to FIG. 3, all six quadrilateral faces 20, 30, 40, 50, 60, and 70 of the toy block in FIG. 1 are shown with coupling surfaces 80. With respect to a two cubic inch sized toy block 10, segment S1 has a length of 0.75 inches, as measured from the center point (not shown) of the peg 82, 84 to the edge E of the block 10. Segment S2, from the center point (not shown) of each connector peg 82, 84 to each connector hole 86, 88 measures 0.50 inches.

With reference to FIG. 3A and continuing reference to FIG. 3, displacement indicia lines 110, 120 and 130 are drawn in a set of X,Y coordinate graphs. Each of the graphs is composed of a horizontal X axis with six evenly spaced points and a vertical Y axis with six evenly spaced points. Indicia lines 110 are each crossed by a single perpendicular line at the midpoint, run from point (0,4) to point (1,0) on the leftmost graph, and connects all perpendicular edges on faces 20 and 60. Indicia lines 120 are each crossed by two perpendicular lines at or nearby the midpoint, run from point (0,5) to point (2,0) on the central graph, and connect all perpendicular edges on faces 30 and 50. Indicia lines 130 are each crossed by three perpendicular lines at or nearby the midpoint, run from point (0,6) to point (3,0) on the rightmost graph, and connect all perpendicular edges on faces 40 and 70. The leftmost graph is equivalent to a scale representation of the bottom half of the left edge, the left half of the bottom edge, and the bottom left indicia line of face 20 and 60. The central graph is equivalent to a scale representation of the bottom half of the left edge, the left half of the bottom edge, and the bottom left indicia line of face 30 and 50. The rightmost graph is equivalent to a scale representation of the bottom half of the left edge, the left half of the bottom edge, and the bottom left indicia line of face 40 and 70.

Referring to FIG. 4, a non-limiting example of a coupling region 80 is illustrated. The pair of connector pegs 82, 84 and the pair of connector holes 86, 88 are cubic shaped, while still complimenting one another such that the connector holes 86, 88 receive the connector pegs 82, 84. It will be appreciated by those of ordinary skill that both the pegs 82, 84 and the holes 86, 88 can take on other non-circular and alternate shapes for providing frictional engagement.

As illustrated in FIG. 5, toy block 10 includes face 20 with four sets of coupling regions 80. In this configuration of FIG. 5 with four coupling regions 80 on a two cubic inch block, the coupling regions 80 are sized such that segment S1 has a length of 0.35 inches, as measured from the center point (not shown) of the peg 82, 84 to the edge E of the block 10. Segment S2, from the center point (not shown) of each connector peg 82, 84 to each connector hole 86, 88 measures 0.30 inches.

With reference to FIG. 6, two interconnected toy blocks 10A and 10B are shown. When the connector peg 82, 84 of block 10A corresponds to the connector holes 86, 88 of block 10 b, and vice-a-versa an audible stimulation, such as a “click,” is produced, affirming frictional engagement between the two blocks 10A and 10B.

As illustrated in FIGS. 7 and 8, blocks 10 may have only one face 20 with a coupling region or regions 80. All other faces on such blocks are flat. FIG. 7 is cuboid. FIG. 8 contains a face that is sloped in relation to the face which has a coupling region 80, and two sides that are trapezoidal in shape. These finished-face type blocks 10 can be used to form the outer surface of the to-be-built static structure (See also FIG. 9).

In FIG. 9, block set 100 includes toy blocks 10 interconnected to provide an exemplary static structure. Block set 100 exemplifies the following blocks: blocks 10 with a diameter of two inches on each edge; blocks 10 with a diameter of one inch on each edge; blocks 10 with only one coupling region 80 and a diameter of two inches; blocks 10 with only one coupling region 80 and a diameter of one inch that are cuboid; blocks 10 with only one coupling region 80 and a diameter of one inch that have a sloped surface; blocks 10 with only one coupling region 80, a diameter of two inches along each straight edge, and a seventh face that is curved 101; and blocks 10 with a diameter of two inches on each edge and four coupling regions 80 on one face 20.

From the foregoing description it will be apparent that modifications can be made to the toy block 10 and block set 100 without departing from the teachings of the invention.

The instant invention may be embodied in other forms or carried out in other ways without departing from the spirit or essential characteristics thereof.
